MVVM

MVVM (Model-View-ViewModel) is a software architectural pattern that separates an application's user interface (View) from its business logic (Model) using an intermediary layer called ViewModel. It is commonly used in GUI-based applications, particularly with frameworks like WPF, Xamarin, and Angular, to enable data binding and improve testability. The pattern promotes a clear separation of concerns, making code more maintainable and scalable.

Also known as: Model-View-ViewModel, MVVM Pattern, MVVM Architecture, MVVM Design Pattern, M-V-VM

Why learn MVVM?

Developers should learn MVVM when building complex, data-driven applications where UI and business logic need to be decoupled, such as in desktop, mobile, or web apps using frameworks that support data binding. It is especially useful for scenarios requiring unit testing of UI logic without UI dependencies, as the ViewModel can be tested independently. MVVM also facilitates team collaboration by allowing designers and developers to work on separate components.
